TYPEWRITNG MACHINE.

Application filed June 30, 1924, Serial rlhis invention relates to typewriting inachines, and more particularly to devices used in connection therewith to facilitate typing cards, with special reference to library filing cards having peculiarly out end edges. Considerable drliiculty is ordinarily encountered in typing such relative lv narrow cards because ot their notched and perliorated end edges, which interfere with the iront scale and other parts of the inachine, louling thereon and becoming displaced to the annoyance et an operator and spoilation oi the cards.

@ne oit the features 0l: this invention is 1n the provision ot a card-holder, that can be instantly and easily applied to a typewriting machine arranged to receive the same, in which a card is positively held at its ends, iliarallel with the pla-ten, and snugly againstits surface central ot its length.

iinother feature is in the provision of means which securely loclr the device to the platen at both ends, the locking means be- 'ing readily released Without soiling the tingcrs or the use ol tools. l

lt is a lurther purpose to provide a W1ngscale, movable into upper and lower case positions With the platen and arranged not to interfere with the card-holder; and to itin-ther provide a card-guide directly engageable on the wingscale, which also avoit conlliction. y

llthcr features and advantages will hercinalfter appear'.

ln the drawings, the numeral l() designates a fragment of a type-bar and head, actuated as usual from the keyboard ot a typewriting machine to strike against a i platen ll. This platen is mounted on a No. 723,176. Renewed June l, 1935.

shaft l2 journaled in a platendrame having ends 13 and being provided with an ordinary twirling knob let tor manual rotation, and a toothed line-space wheel l5 for its ordinary operation. Each type-head commonly carries two types,` respectively, upper and lower case, and the platen-:trame is shifted up and down by means (not shown) to bring a printing point l?. into registration with either type, in addition to its longitudinal letter space and return movements, as will be understood.

jl cardholder l@ is composed ot a. thin sheet oit material having a central, parallel edged body-portion l, curved in cross-sec tion to conform closely to the periphery of the cylindrical platen ll., over nearly hall the areaoi which it is disposed for at least the length olf a card to be typed, suoli card being generally indicated by the numeral 1S. Vlhe end portions il) ot the card-holder have convergingly inclined edges which extend to the end oi the platen and then bend at right angles to produce linirallel-edged extendingv llanges S20', terminating in torlrs 2l having between them slots or recesses 22 to engage flattened portions 23 ot the shait l2, adjacent the ends et the platen, so that, as the platen is rotated, the card-holder will turn with it.

Mounted on the flanges E20, by pivots 2d, are fiat catches 25, their hook elements 2G being shaped to swing around the shaft l2 and maintain the cardholder in operative position, the catches being normally held in engagement by coil tension springs El?, one oli' the ends olf each ol' which is secured to pins 28 set in the catches and* the other ends to pins it) set in the llanges 20 and ein tending outwardly through slots 30 in the catches, the swinging movements oi which are limited by the length oit the slots. rllhis construction is best seen in Figure 2, which also shows knobs 3l lined on the catches at their corners, to entend into operative posi# tions adjacent the periphery of the platen,

these knobs obviously being arranged tor c convenience in releasing the catches When applying or removing the card-holder.

A rectangular opening or pocket 33 is formed centrally in the body-portion 17 oi" the card-holder, its width being in excess ot the width of the card 18, and at the ends ot the opening are recesses 34- into (lll Gli

Elli

lill] whichv the ends of the card neatly fit to be guided at their side edges, while their end edges make contact at the bottomsof the recesses, as the combined depth of the r'ecesses and length of the opening equals the full lengthot the card, as can be seen in Figure 4. The bottoms of the recesses thus form side gages.

Spring clips are held over the recesses 34 by rigidly securing one end 37 of each clip to the body 17 of the card-holder, these clips bein(7` bent concentrically and inset to produce clamps 3S, raised at their 'ree outer ends toV constitute guides 39, overly ingthe opposite margins ot' the recesses and shaped to .receive a card therebelow which may be slipped readily into the recesses and openingv to rest directly 'upon the platen.

Thus the cards are held i'rom movement longitudially and laterally and retained spring-pressed against the platen. Vhen it is desired to remove the card its side edges are grasped by the fingers of an operator l entered at the spaces between the card edges and the edges of the opening thus raising the card by drawing its ends from below the clip. The card is entered by placing it y in a position as shown in Figure 4 and pressing it sidewise below the raised guides 39 until seated on the platen.

AV wing-scale 40 ot spring material is secured` at its lower, offset edge by screws 41 to a floating scale frame 42, which comprises a cross-bar 43, carried by the platen shiftirame 44, and guided verti lally by a pair of integral upstanding shields 45, bent 'ups ward from the lower edge of the scale and containing elongated slots 4G shaped to receive rollers 47 carried at the ends of spring brackets 48 Iixed by screws 49 to a type-bar segment 50. The rollers 47 have hubs 5l on each side, pressingagainst the slotted shields, tending to steady the Heating scale frame and prevent it from moving longitudinally.

The wing-scale 40 has-a central opening 52 in its upper portion through which type pass :in strikingvthe platenat the printing point X, and also contains slots 53 extending in from their lower edges, permitting their lower side portions to be bent angularly outward to the offset attaching portions on the scale trame. V, Y y

Onthe upper front Asurface of the scale, equi-distant from the center, are iixed two button-headed studs 56 by which is engaged a card-guide 57.'` The card-guide is composedl of a spring bow smoothly rounded on its vinner surface and curved to conform to The apex 58 or' the card-guide readily over thev card-holder and is provided with a linger-piece 59 by which it may be manipulated.

The diverging branches 60 of the bow blend into flat pads Gl disposed over the surface ot the wing-scale 40, these pads being shaped to present lateral extensions G2 engageable on the studs 5G below their heads, and downward extensions 63 to engage between the studs, their lower extensions being bevel-ed to facilitate entry therebetween, slightly springing the branches of the bow in so doing and iirmly holding the cardguide in position.

The extreme lower ends oi the pads Gl are bent to torni detents G4, which engage below projecting ledges G5 on the lower edge or the wing-scale, acting to retain the card-guide on the. scale until forcibly removed, and the ends of the card-guide extensions 62 are bent out at right angles to provided lugs (SG to make contact with the rear surface oi the shields 45, the arrangement heilig shown in Figures l and 3.

It is deemed desirable to prevent a full rotation of the platen when typing such cards andV permit it to turn only suiicient ier the convenient entry of the cards and the tvping thereon. This is accon'iplished by tixing rigidly at one end ot the platen, pins (i7 and G8, the same extending suiiiciently outward to engage on opposite sides of a stop (i9. at the end oi an arm 70, extending from a bracket 7l, secured to the adjacent platenframe end 13.

Obviously the location of the pins will determine the amount oi rotation that can be imparted, and thus the card-holder and platen are held in position ready for use without unnecessary rotation.

Variations may be resorted to within the scope of the invention, and portions ot the improvements may be used without others.

Having thus described my invention, I claim:
